Stahl Arms

Stahl Arms is the Helghast's largest arms corporation, focusing on weapons development and production for the Helghast military. It was founded by Khage Stahl, the father of Jorhan Stahl (who, during the events of Killzone 2 and Killzone 3, and likely before, is the current CEO). Their largest competitor is Visari Corporation, the family company of Autarch/Emperor Visari himself.

The key feature to almost all Stahl weaponry is a high rate of fire. Their most famous model is the StA-52 Assault Rifle, appearing in all phases of the Second Extrasolar War and being the standard firearm for the Helghast military.

In contrast to Visari Corporation, which focuses more on high-end weapons and technologies, Stahl Arms largely concentrates on developing and building mass-produced infantry weapons and armor for the Helghast forces. However, development facilities producing extremely high-tech weaponry and vehicles are known to exist, such as facilities that produce towering MAWLR walkers, destructive experimental StA-5X Arc Cannons, nimble StA-X6 Jetpacks, and even space warships armed with planet-destroying irradiated petrusite missiles and protected by thick energy shielding. Apart from that they maintain a small private army composed by HAZMAT Trooper and Capture Trooper

A subsidiary of Stahl Arms is tasked with mass producing Body Armor, including helmets, jackets, and other pads worn by the Helghast military. The main supplier was Corinthmetall.

After the Terracide, Jorhan Stahl gathered survivors and began building an army with the intention of invading Vekta. Many of the weapons built for said army were products of Stahl Arms, including MAWLRs and weapons used by the New Helghan government. Stahl Arms still supplies the New Helghan government with weapons as of 2381. As well as supplying the Black Hand with weapons and technology to attack the Vektans.

The third section of Killzone 2's first mission, Corinth River, takes place within a Stahl Arms warehouse.

The Stahlhelm was the main infantry helmet of both World Wars for the German army (since Stahl simply means "steel").

Stahl Arms was released as a multiplayer map in the Steel Rain Pack in Killzone 3.

The 26th episode of season 7 (and the current series finale) of the animated comedy "Futurama" features a character in a diamond store gag with a tattoo on his left arm that looks similar to the Stahl Arms logo from Killzone 3.
